Thank you soooooooooooooooooooooo much. So far, I've been having a decent time in calculus, but those physics problems annoyed me. This helped me understand what my book was telling me.
Hello. Sorry, I'm confused. The chain rule = plugging in the inner function into the derivative of the outer function and then multiplying that by the derivative of the inner function. When you used the chain rule on the LHS and RHS, what exactly were the outer & inner functions? Also, why do the variables simply changing over team mean we have to use the chain rule? Thanks.
Hey, thanks for the question. On the left side, I am treating V as V(t), so V is the outside function and t is the inside function. And on the right side, similarly the r is a function of time r is the outside function and t is the inside function even if it isn't written. The variables changing over time makes the inside function of t which is why we use the chain rule. Let me know if that clears it up!
Thanks so much for this, I couldn’t figure it out to save my life
So glad it helped!

@@HomeworkHELPTutor It does. Thanks!
Great, no prob!
good video
Thank you
such a civilized comment section, btw can you solve my pfp
Haha, I'm so glad to have civilized commenters :-) but sorry, not sure what problem you are asking about
